Later Roman art does not show women with the frequency or diversity it does men. Very often the women who are shown are there often to be paradigms of modesty and piety. This picture is one in that mould. This outfit might be what a modest and pious woman of the peasant class would have been wearing, although realistically it would be rare for her dress to be quite so plain. In this paradigm such a woman would not have been seen in public without a cape. Her simple headdress was called βηλάριον / vêlarion by the middle Byzantine period.
